A2A Simulations has recently released a native build of their Accu-Sim Comanche 250 for Microsoft Flight Simulator 2024, including new 2024-only features such as the new EFB apps, dirt accumulation, and more.

​

The upgrade brings native 2024 gauges, a native 2024 EFB with charts and other apps, a full walkaround system using 2024’s standards, dirt accumulation on the exterior, dual PMS/TDS GTN 750/650 configuration, time compression support, and much more. The complete feature list follows below:

• Brand-new Accu-Sim 2.0 “Merlin” external aerodynamics engine, developed from a clean slate
• Performance accuracy based on many years of operating A2A’s own Comanche 250 (N6229P)
• Exceptional aircraft feel, handling, and trim behaviour driven by extensive real-world flight testing
• Full physics-based per-cylinder simulation of the Lycoming O-540-A engine
• Advanced engine starter simulation that physically turns the engine through compression cycles
• Authentic fuel system modelling fuel lines, primer, strainers, and contamination
• Custom oil system with dynamic viscosity, degradation, and colour changes over time
• Detailed JPI EDM-830 engine monitor with authentic displays and leaning procedures
• Graphical tablet-based engine analyser providing deep insight into piston engine operation
• Dynamic ground physics with true weight-on-wheels modelling and tyre side-loading
• Realistic response to different runway and surface types
• Advanced turbulence response and subtle wing flex based on airflow, bumps, and fuel load
• Sophisticated airframe vibration physics with unique ground roll and engine-driven effects
• Physics-driven sound environment with hundreds of dynamic sound effects
• Fully native MSFS2024 model and gauges with optimised LODs
• Native MSFS2024 EFB integration, allowing the tablet to display charts and supported EFB apps
• Full MSFS2024 walkaround system with many interactive and inspectable components
• Persistent exterior dirt accumulation between flights
• Beautifully rendered exterior and interior with subtle wear effects and advanced animations
• Dynamic aircraft registration decals
• Custom-coded Narco avionics stack, including COM/NAV, DME, transponder, audio panel, and ADF
• Narco NS-800 RNAV configuration for classic, non-GPS RNAV flying
• Century NSD-360A HSI with custom needle-smoothing physics
• Advanced simulation of the S-TEC System 30 two-axis autopilot
• Optional STEC ST-901 GPSS module for GPS-coupled autopilot operation
• Flexible GPS integration options: MSFS / Working Title GNS 430W & 530W, PMS GTN 750/650, and TDS GTNxi 750/650
• Optional Asobo G5 electronic instrument retrofit
• Fully customisable persistent aircraft with adjustable wear and failure simulation
• Pilot’s tablet for intuitive aircraft configuration and management
• Real-time load manager with dynamic weight and balance indication
• Electrical system analyser with functional circuit breakers
• Two naturally animated rear-seat passengers and support for native MSFS avatars in the front seats
• Support for time compression and other quality-of-life improvements
• Fluid in-sim performance comparable to default aircraft of the same class

It’s available in their store for $49.99, and owners of the MSFS 2020 version can upgrade for a discounted price ($14.99). The upgrade is not mandatory, and the previous version will continue to work in 2024, albeit without the new features.
